Mental rotations

The aim of the mental rotation research is to find out factors that are responsible for speed and accuracy of mental rotation task of the Shepard-Metzler paradigm. The research takes into account the impact of the factors such as: features of the presented objects (contour complexity, the complexity of the different number of components, time and frequency of exposure, morphology, aerodynamics), the principle of rotation of the object (shift of the point of rotation in relation to the center of gravity), the form of visual scene presentation (3D exhibition, the position of the horizon of visual scenes, contextual markup minimization), the features of the tested subjects in the paradigm of individual differences (level of execution of the Witkin test, the style of mental constructing of an object’s visual model, the individual characteristics of mental rotation process, the body position of the observer). All experiments are conducted by using the eyetracker technique.

Perceptual complexity

The research is focused on looking for the determinants of the perceived complexity of visual objects. In the experiments we try to establish the relationship between functional dominance of a hand and the perception of the complexity as well as between the level of performance of the Witkin test and the frequency and amplitude of the β rhythm (13-18 Hz) (EEG technique).

Comprehension of Audiovisual Communication

Studies of the influence of prosody (accent, intonation, quantity) in the spoken off-screen text (behind the frame) on the understanding of the content of television news programs. Research on brain correlates of the image cuts implemented in the ERP paradigm.

Change Blindness in Visual Scene

The aim of the study is to verify hypotheses regarding the behavioral and neurophysiological determinants of change blindness that occurs in the so-called critical fixation points, ie. when the eye fixation takes place just before and just after the change occurs. The experiment is based on a unique method of MMF (Fixation Related Potentials) which is a combination of the ERP method (Event Related Potentials) and the eyetracker method for measuring eye movements.

False Recognitions

The project aims to study brain activity while memorizing lists of words that causes the formation of false recognitions. Experiments are carried out by the technique of brain evoked potentials associated with the events ERP (Event Related Potentials).
